Gasoline flow meter, also known as turbine flow meter, is a turbine flow meter that has been optimized and designed based on domestic and foreign flow meter technology. It has the characteristics of simple structure, lightweight, high accuracy, good reproducibility, sensitive response, and easy installation, maintenance, and use. It is widely used to measure liquids in closed pipelines that do not corrode stainless steel 1Cr18Ni9Ti, 2Cr13, corundum Al2O3, and hard alloys, and have no impurities such as fibers or particles. The flow meter can be used for liquids with a kinematic viscosity of less than 5 × 10-6m ²/s at working temperature. For liquids with a kinematic viscosity greater than 5 × 10-6m ²/s, the flow meter can be calibrated for real liquid before use. If paired with display instruments with special functions, it can also perform quantitative control, over limit alarm, etc., making it an ideal instrument for flow measurement and energy conservation.

| vantage | drawbacks | |
| 1 | There are no moving parts and no throttling parts in the measuring tube to impede the flow of fluid, which does not cause any additional pressure loss when the fluid passes through the meter. | It can only measure the liquid flow of conductive media, not the flow of non-conductive media |
| 2 | Electromagnetic flow meters can be used to measure the flow of other electrically conductive liquids after calibration with water only. | Cannot be used to measure gases, vapors, or liquids containing large quantities of gases. |
| 3 | Their range ratios can be up to 20:1, and some even up to 100:1 range ratios. | The medium in the pipe must be full, and cannot be measured out of a full pipe. |
| 4 | No mechanical inertia, sensitive response, can measure instantaneous pulsating flow, positive and negative direction of flow | Can only be measured above DN10 pipe, not applicable to small diameter |
| 5 | Measure the flow of corrosive media, spoiled media and suspended liquid-solid two-phase flow. | Cannot measure hydrofluoric acid media |
1, should be installed in the horizontal pipeline lower and vertically upward, avoid installation in the pipeline *** point and vertical downward;
2、It should be installed at the rising place on the pipeline;
3, in the open discharge pipeline installation, should be installed in the lower part of the pipeline;
4、If the pipeline drop is more than 5m, an exhaust valve should be installed downstream of the sensor;
5, should be installed downstream of the sensor control valves and shut-off valves, and should not be installed in the sensor upstream;
6, the sensor *** can not be installed in the pump inlet and outlet, should be installed in the pump outlet.
